I've done some efficiency tests on work units on WCG and the my nexus 4 (snapdragon s4) consumes 4.8 watts when the battery isn't charging. The credits I get are twice what I get per watt on my core 2 duo laptop underclocked and undervolted. Now I gotta see if this nexus 4 can be undervolted without rooting =)
